They're both unspecified. The one on the left is hopefully recognisable as a hadrosaur. I made the one on the right purposefully ambiguous. It looks like a dromaeosaur at a glance, but you may notice its lack of a sickle claw and what appears to be a beak. Really, it's a little ornithischian made to look like an overblown maniraptor, complete with wings.

It's a gentle parody on 'feather overload', as Marc would put it. There's welcoming the idea that many dinosaur clades were indeed feathered, but there's zealously feathering every dinosaur imaginable, even ones for whom extensive scale covering has been discovered; like hadrosaurs, for instance. There's also recognising that even the proven feathered ones may not have necessarily been puffballs or so exactly like modern birds (Emily Willoughby covered a similar topic recently on her blog too).
